The Original Growler Mountain Bike Race

The Original Growler is a legendary endurance mountain bike race held each year in Gunnison, Colorado, featuring challenging singletrack and rugged terrain at Hartman Rocks.

Known for its grassroots spirit and strong community support, the event brings riders together for a true test of stamina, skill, and perseverance while raising funds for local trail building and maintenance through Gunnison Trails.

With multiple course options and a lively post-race celebration, the Growler has become a cornerstone of Colorado’s mountain biking culture.

All proceeds benefit Gunnison Trails, a 501(c)(3) nonprofit dedicated to maintaining and expanding the singletrack experience in the Gunnison area.
